The Museum of Curiosity (6.30pm, Radio 4) is "a great big hungry baby suckling on the teat of knowledge", according to the comedian Bill Bailey, who co-hosts the show alongside veteran TV producer John Lloyd. If that leaves you none the wiser - and it would, wouldn't it? - you might prefer to think of it as a new panel show in which an unusual mix of entertainers, academics and scientists tackle an equally eclectic bunch of subjects. How unusual? How eclectic? Well, by the end of the six episodes guests ranging from Alan Davies, Ben Elton and Brian Blessed to paleontologist Richard Fortey and pigments expert Victoria Finlay will have plumbed the shallows of the Big Bang, pubic hair, Father Christmas, dadaism, yetis, 196,883 dimensional space, pineapples, Epping Forest and, er, nothing.

If that doesn't float your boat, how about a nice psychological thriller? Cobwebs (2.15pm, Radio 4), by David Hodgson, follows a man called Greg whose attempt to recover his wife's death is scuppered by a mysterious woman in plastic shoes.
